Abstract
Now days, the construction sector is exploring rapidly on a large scale and also involves new techniques for rapid and comfort works on the field. Concrete as a building material plays an important role in this sector. The consumption of natural resources as an ingredient of concrete, costs high as well as it is on verge of extent. These problems force us to recover the natural resources or to find an alternative option to overcome this problem. Presently, the production of waste foundry sand as a by-product of metal casting industries causes various environmental problems. Foundry sand is basically high quality silica sand which is a by-product of both ferrous and non-ferrous metal casting industries. This paper reviews the Utilization of waste foundry sand in Civil Engineering field. It comprises the important findings from the experimental works of many researchers. Due to over dependence on non-renewable energy material is becoming an imminence and therefore it is necessary to look for the possibility of recycling. Generation of waste foundry sand as by-product of metal casting industries causes environmental problems due to its inappropriate disposal so it can be used as a partial replacement of the fine aggregate with the foundry sand in concrete. It was observed that about 15-30% of replacement of fine aggregate to waste foundry sand gave good result for all practical purpose.
